Loki Patera / ˈ l oʊ k i ˈ p æ t ə r ə / is the largest volcanic depression on Jupiter's moon Io, 202 kilometres (126 mi) in diameter. [2] It contains an active lava lake , with an episodically overturning crust. [ 3 ]
The discovery of volcanic plumes at Pele and Loki in 1979 provided conclusive evidence that Io was geologically active. [1] Generally, plumes form when volatiles like sulfur and sulfur dioxide are ejected skyward from Io's volcanoes at speeds reaching 1 kilometre per second (0.62 mi/s), creating umbrella-shaped clouds of gas and dust.

Tvashtar Paterae compose an active volcanic region of Jupiter's moon Io located near its north pole. It is a series of paterae, or volcanic craters. It is named after Tvashtar, the Hindu god of blacksmiths. [1] Tvashtar was discovered in IRTF images on November 26, 1999, several hours after a Galileo flyby.
On Io, catenae / k ə ˈ t iː n ə / (crater chains, sg. catena) are named after sun gods in various mythologies. In 2006, the use of the term catena was discontinued in favor of the patera / ˈ p æ t ə r ə / (plural paterae / ˈ p æ t ə r iː /). Below is a list of features that previously used the descriptor term catena.
The names of regions on Io use a combination of a name derived from locations in Greek mythology associated with the nymph Io or Dante's Inferno, or from the name of a nearby feature on Io's surface and the descriptor term, regio, Latin for region. Coordinate, diameter, and name source below come from the IAU's Solar System Nomenclature Website ...
These volcanic mountains are often smaller than the average mountain on Io, averaging only 1 to 2 km (0.6 to 1.2 mi) in height and 40 to 60 km (25 to 37 mi) wide. Other shield volcanoes with much shallower slopes are inferred from the morphology of several of Io's volcanoes, where thin flows radiate out from a central patera, such as at Ra Patera .
